The population structure, life cycle, and abundance of the copepod Limnocalanus macrurus, one of the two multicellular zooplanktonic species in Char Lake, Northwest Territories, has been studied for 18 months. The population is univoltine, taking about 9 months to develop from egg to adult. Total population density was lower in 1970 than in 1969, whereas the phytoplankton biomass and productivity was virtually identical in both years. The life cycle of L. macrurus was very similar in both years of study and also showed close similarity to that of a southern Ontario population.
